Referring to FIG. 1, Fig. 1 is a kind of schematic diagram of motorcycle track phase-separating section provided herein.As shown in Figure 1, one
As, it along locomotive driving direction, sets gradually there are four magnetic signal conveyer, wherein the first magnetic signal conveyer G1 and the
Two magnetic signal conveyer G2 are arranged before non-Electric region, and third magnetic signal conveyer G3 and the 4th magnetic signal conveyer G4 setting exist
After non-Electric region.
The magnetic signal that first magnetic signal conveyer G1 is sent is referred to as " anticipating signal ", for reminding in front of locomotive nearby
Non-Electric region will be entered and carry out commutation power supply, it is therefore desirable to railroad traction unloading is carried out, it is disconnected to be offloaded to zero in railroad traction
Open main circuit breaker.In this way, contact net is not charged in non-Electric region, while train main circuit breaker disconnects, the traction of locomotive and vehicle-mounted
Power supply is just no longer powered by contact net.At this point, in general, in order to guarantee the lasting confession in non-Electric region to vehicle assistant load
Electricity, locomotive can take a little " braking ", and traction electric machine switchs to Generator Status, be powered using the kinetic energy of locomotive to vehicle electronic circuit.
And in order to ensure locomotive drives into non-Electric region in the state that main circuit breaker disconnects, it is typically provided with before non-Electric region
First safe trough, the second magnetic signal conveyer G2 is just mounted at the start position of the first safe trough, when train row
It sails to " the strong break signal " for receiving the second magnetic signal conveyer G2 transmission herein, no matter railroad traction is either with or without unloading at this time
To zero, automatic passing over of neutral section controller can all be forced to disconnect main circuit breaker, to ensure that locomotive is entered with the state that main circuit breaker disconnects
Non-Electric region.
Similar with the first safe trough, locomotive will be by that will enter the second safe trough, third magnetic letter after non-Electric region
Number conveyer G3 is just mounted on the terminal point of the second safe trough, for sending " restoring signal " by locomotive herein,
In order to make automatic passing over of neutral section controller is closed main circuit breaker, then restore traction output.Generally, the first magnetic signal conveyer G1
This section of overall area between third magnetic signal conveyer G3 is known as " phase-separating section ".The signal that 4th magnetic signal conveyer G4 is sent is simultaneously
There is no practical significance, is intended merely to the needs of locomotive two way on route and is arranged.
In phase-separating section schematic diagram shown in FIG. 1, the length of the length distance of the first safe trough and the second safe trough
Spending distance is S2.Length distance between first magnetic signal conveyer G1 and the second magnetic signal conveyer G2 is S1.
Referring to FIG. 2, Fig. 2 is the railroad traction unloading side during a kind of locomotive automatic passing over of neutral section provided herein
The flow chart of method is applied to automatic passing over of neutral section controller, mainly comprises the steps that
Step 1: after the anticipating signal for receiving the first ground magnetic signal conveyer G1 transmission, persistently obtaining locomotive
The current distance S of present speed v and locomotive and the first safe trought。
Step 2: according to present speed v and current distance StResidue needed for calculating locomotive operation to the first safe trough
Time Tt。
Specifically, it needs to accelerate when locomotive driving is in upward slope operating condition, railroad traction is specially tractive force；And work as motor supply shop
It sails and needs to slow down when descending operating condition, railroad traction is specially electric braking force.Locomotive needs to hold before climbing and during climbing
Continuous output tractive force is to provide power, if unloading tractive force must cause the later period to be short of power and stop in advance.And locomotive is under
It needs to start output electrical system power during slope to control speed, if unloading electric braking force too early, is likely to result in hypervelocity, increase
Add the traffic safety risk of locomotive.
Specifically, in the railroad traction discharging method in process of vehicle passing through phase breaking provided herein, there is no as existing
Have in technology with regard to carrying out railroad traction unloading at once like that after receiving anticipating signal, but temporarily first keeps current locomotive
Power traveling, and constantly update calculating locomotive and run with present speed to remaining time T needed for the first safe trought, directly
To remaining time TtStart to carry out railroad traction unloading again when meeting preset condition, to make full use of locomotive when going up a slope
Kinetic energy enables locomotive run at high speed for a long time as far as possible, avoids kinetic energy waste caused by unloading too early and parking accident, and under
Guarantee abundant braking deceleration, guarantee driving safety when slope.Therefore, when receive the first ground magnetic signal conveyer G1 transmission it is pre-
After accusing signal, the present speed v and locomotive of automatic passing over of neutral section controller sustainable renewal acquisition locomotive and the first safety are pre-
Stay the current distance S in areat, and then according to present speed v and current distance StCalculating is run at this time to needed for the first safe trough
Remaining time Tt:
Tt=St/v。
It is easily understood that the current distance S of the described safe trough of locomotive and firstt, actually refer to locomotive
At a distance from the first safe trough start position i.e. the first magnetic signal conveyer G1 installed position.Further, since motor supply shop
Sail speed and traveling-position be it is continually changing, therefore, the current distance S of present speed v, locomotive and the first safe trought
All constantly detected in real time.
Step 3: as remaining time TtEqual to preset duration TsetWhen start with preset slope k unloading vehicle power.
Step 4: after railroad traction is offloaded to zero, before locomotive enters non-Electric region, disconnecting main circuit breaker.
Wherein, preset duration TsetFor railroad traction to be preset to duration needed for slope k is offloaded to zero；Non-Electric region is located at
After first safe trough；Railroad traction is tractive force when locomotive accelerates, and is electric braking force in locomotive deceleration.
Specifically, locomotive is usually and unloads by fixed slope k when carrying out railroad traction unloading, therefore, will be initial
Duration required for the railroad traction at moment is offloaded to zero i.e. preset duration TsetIt is known computable:
Tset=Ftb_0/k；
Wherein, Ftb_0The as locomotive railroad traction of carving output at the beginning.
As the remaining time T being calculatedtEqual to preset duration TsetWhen, then illustrate locomotive from this moment on default oblique
It is zero by just railroad traction is unloaded at operation to the first safe trough when rate k unloading vehicle power.This Shen as a result,
Please provided by railroad traction discharging method, be just specifically to detect remaining time of the locomotive driving to the first safe trough
TtEqual to TsetWhen just start carry out railroad traction unloading, can enable as a result, railroad traction locomotive enter the first safe trough when
Just it is offloaded to zero,
As it can be seen that being received in railroad traction discharging method during locomotive automatic passing over of neutral section provided herein
It crosses after the anticipating signal of split-phase, the remaining time T of locomotive driving to the first safe trough is calculated by constantly updatingt, and
Until remaining time TtJust start to carry out railroad traction unloading when meeting preset condition, to ensure railroad traction default
It is just offloaded to zero at the start position of the i.e. first safe trough at place, not only effectively prevents tractive force when accelerating that goes up a slope
The problems such as locomotive follow-up driving force caused by unloading in advance is insufficient also avoids when downhill retardation caused by brake force unloads in advance
Locomotive hypervelocity the problems such as, so as to effective guarantee locomotive smoothly, safely by non-Electric region, reduce traffic safety risk.
Power discharging method during locomotive automatic passing over of neutral section provided herein, on the basis of above-described embodiment
It is upper:
As a kind of preferred embodiment, as remaining time TtEqual to preset duration TsetWhen start with default slope k unloading
After railroad traction, further includes:
If railroad traction is not offloaded to zero when locomotive enters the first safe trough, the second ground magnetic is being received
Main circuit breaker is disconnected after the strong break signal that signal transmitter G2 is sent；
Wherein, the second ground magnetic signal conveyer G2 is installed on the start position of the first safe trough.
Specifically, due to the difference of road conditions and service condition, in some special cases, locomotive may still have been will appear
It is travelled to starting point i.e. the second ground magnetic signal conveyer G2 installed position of the first safe trough but railroad traction is not yet
The case where being offloaded to zero.Therefore, after receiving the strong break signal of the second ground magnetic signal conveyer G2 transmission, regardless of this opportunity
The unloading what state of vehicle power, automatic passing over of neutral section controller can all block railroad traction at once, then disconnect main circuit breaker, with
Just ensure that locomotive will not drive into non-Electric region with load.In this way, although locomotive is not received by anticipating signal, due to strong break signal
Effect, locomotive can also smoothly complete individual-phase control process.
As a kind of preferred embodiment, as remaining time TtEqual to preset duration TsetWhen start with default slope k unloading
After railroad traction, further includes:
After locomotive passes through non-Electric region and the second safe trough, sent receiving third ground magnetic signal conveyer G3
Recovery signal after, closure main circuit breaker simultaneously load railroad traction；
Wherein, the second safe trough is located at after non-Electric region, and third ground magnetic signal conveyer G3 is installed on the second peace
The final position of full trough.
Specifically, when locomotive have received third ground magnetic signal conveyer G3 transmission extensive time multiplexed signal, illustrate locomotive
Non-Electric region and the second safe trough are had already been through, then can be restored gradually at this time to the normal smooth-ride state of locomotive.
Firstly, automatic passing over of neutral section controller needs to reclose main circuit breaker, to be obtained using pantograph from the contact net after commutation
Electric energy；Then railroad traction is gradually loaded again, restores the travel speed of locomotive, so that completion is once complete to cross individual-phase control stream
Journey.
It should be noted that the contact net in non-Electric region is not charged, during locomotive drives into non-Electric region, can detect
The voltage of contact net then can detect network pressure from scratch during sailing out of non-Electric region from the variation phenomenon having to nothing
Variation phenomenon.The foundation of non-Electric region can be do enter into using the interruption variation phenomenon of contact net voltage as judgement locomotive as a result,.
It is easily understood that considering for operational safety, in the automatic passing over of neutral section control process of locomotive, in each stage
Settable certain delay time between each operation.In addition, also further signal received before can be confirmed, with
Anti- error.
As a kind of preferred embodiment, the operating range after locomotive receives anticipating signal increases to the first pre-determined distance
In a period of, if not receiving strong break signal and being not detected through the network pressure variation phenomenon behind non-Electric region, determine to predict
Signal is error signal, and carries out corresponding maloperation processing.
Specifically, due to the presence of certain factors, there may be situations such as mistaking signal.Therefore, the application can be with
Further the signal received is tentatively judged, to reject error signal.For anticipating signal, under normal circumstances, when connecing
After receiving anticipating signal, locomotive will enter back into non-Electric region into the first safe trough after travelling a distance again, institute
Can detect the network pressure variation phenomenon in strong break signal and non-Electric region.If after locomotive driving sufficiently long range always
The sign into the first safe trough and non-Electric region is not detected, then received anticipating signal is accidentally to transmit before explanation
Number, automatic passing over of neutral section control flow thus can be exited, executes and restores the maloperations such as railroad traction processing.
As a kind of preferred embodiment, the first pre-determined distance specifically:
Sp=2 (S1+S2)+S3；
Wherein, Sp is the first pre-determined distance；S1 is the first ground magnetic signal conveyer and the second ground magnetic signal conveyer
Between mounting distance；S2 is the length distance of the first safe trough and the second safe trough；S3 be non-Electric region length away from
From.
Specifically, the first magnetic signal sensor G1 for sending anticipating signal is just mounted on the distance of S1+S2 before non-Electric region
Place, and in view of factors such as signal delays, the first pre-determined distance Sp can be taken as to the numerical value greater than S1+S2, for example, can be taken as 2
(S1+S2)+S3。
As a kind of preferred embodiment, if locomotive from receiving anticipating signal, to during receiving and restoring signal
Operating range less than the second pre-determined distance, and detect through the network pressure variation phenomenon behind non-Electric region, then determine to restore signal
For error signal, and carry out corresponding maloperation processing.
As a kind of preferred embodiment, the second pre-determined distance specifically:
Sr=S1+S2+S3；
Wherein, Sr is the second pre-determined distance；S1 is the first ground magnetic signal conveyer G1 and the second ground magnetic signal transmits
Mounting distance between device G2；S2 is the length distance of the first safe trough and the second safe trough；S3 is the length of non-Electric region
Spend distance.
Specifically, as shown in Fig. 2, sending the first ground magnetic signal conveyer G1 of anticipating signal and sending recovery signal
The mounting distance of third ground magnetic signal conveyer G3 is S1+S2+S3.In this way, under normal circumstances, when receiving anticipating signal
Afterwards, locomotive should at least travel S1+S2+S3 distance again can just receive recovery signal, so Sr can be taken as the second pre-determined distance
=S1+S2+S3.When locomotive is detected after receiving anticipating signal through the network pressure variation phenomenon behind non-Electric region again, illustrate machine
Vehicle has crossed non-Electric region really, and if locomotive has been received by recovery signal before operating range reaches Sr, just illustrate that this is extensive
Complex signal is error signal, then locomotive should execute corresponding maloperation processing at this time, to prevent the closed procedure to main circuit breaker.
In addition, concrete condition can also be generated to display information and be shown when there is above-mentioned signal mistake heat condition,
So that trainman checks.
